5 Forward visibility
5.1 General
For the seated driving position, the forward visibility requirements of 5.2.1 shall be ensured (see also
A.1 and Annex B).
For the standing driving position, the forward visibility requirements of 5.2.1 shall be ensured (see also
A.2 and Annex B).
The horizontal distance from the driver's eye to the windscreen in seated position shall be a minimum
of 500 mm.
The sightlines as defined in 5.2 shall not be infringed by any permanent equipment of the rolling stock
(except for the wiper), whether inside or outside the cab. ≥
All visibility criteria shall be applied using both dummies defined in 4.2.
Specific visibility criteria apply to driver instructor locations as defined in 5.2.3.
5.2 Forward visibility requirements
5.2.1 Objectives
A good outside field of vision enables the driver to anticipate hazardous situations, taking into account
the exterior environment when the metro vehicle is moving. The cab design shall enable all drivers:
— to see and recognize the signals intended for them in an adequate sighting distance;
— to anticipate and detect hazards by having a large field of vision taking account of the technical
constraints and the physiological data (use of the binocular field of vision).
NOTE Hazards include obstacles on the track, track elements in the wrong position, etc.
These objectives are met if the requirements listed in the following subclauses are fulfilled.
5.2.2 General
5.2.2.1 General characteristics
The visibility for the driver from the normal position respecting the comfort articular angles, as defined
in EN 16186-8 , with the hand on the master control
